ksnyder | July 14, 2010Thanks to the smart nano detectives out there who took a stab at solving yesterday's picture puzzle.
Mystery image #1, aka the "Nano Vortex," shows the different magnetization directions of an arrangement of nickel and nickel oxide. Captured by Center for Functional Nanomaterials (CFN) scientist Yimei Zhu, this photo reveals the local distribution of electromagnetic potential. The ability to directly observe electromagnetic properties at the nanoscale may help scientists engineer new materials that rely on magnetic spin - rather than just electric charge - to control electric current. Such "…
